What is the difference between streamlined and blunt bodies? Is a tennis ball a streamlined or blunt body?
What will be an ideal response?
A body is said to be streamlined if a conscious effort is made to align its shape with the anticipated streamlines in the flow. Otherwise, a body tends to block the flow, and is said to be blunt. A tennis ball is a blunt body (unless the velocity is very low and we have “creeping flow”).
